Intel plans 2013 attack on ARM with next-generation mobile chips

Intel has spoken of its near-future plans to tackle the mobile processor market, where it’s currently being soundly beaten by ARM, whose architecture is used on more than 90-percent of the world’s smartphones. While Intel has already had a go at grabbing some of the market for itself with the Medfield Atom chip, its limited adoption has seen it become largely forgotten.

So what’s next for Intel? Its plan is to forge ahead with the creation of much smaller and more efficient mobile systems-on-a-chip, this time built using a 22nm manufacturing process, which it currently uses for its Ivy Bridge PC processors amongst others. Intel’s current crop of mobile chips are built using 32nm technology, and by shrinking them down to 22nm, they would become the smallest of their type in the world.

All this was announced at the International Electron Devices Meeting which took place in San Francisco earlier this week. Reuters reports that the presentation used at the conference promises the 22nm Intel SoCs, “will be ready for high volume manufacturing in 2013.”

Drawing on experience

This makes it all sound very easy, and while Intel has a certain advantage over its competitors by already building 22nm chips – Qualcomm’s at 28nm and Nvidia’s at 40nm – it’s quite different to try and squeeze all the components not usually associated with PC processors, such as the memory and the radios, onto a single, tiny chip. Intel says its going to overcome this problem by employing the same 3D Tri-Gate transistors it uses in the production of its Ivy Bridge chips.

According to a report by Bit-Tech this would, “provide a significant boost in efficiency,” while an Intel spokesperson said 22nm Tri-Gate chips could offer hardware manufacturers with the option of increased performance from the same amount of power, or to keep the performance the same as 32nm chips while lowering power usage. As standby times and battery performance are becoming more important to us, this could be seen as a considerable benefit.
